` UNITED STATES PATENT OEEICEo ACHILLE BATAILLE, OF NEW YORK, N. Y.

FLEXIBLE JOINT IQ'OR PIPES.

SPECIFICATION forming part of Letters Patent No. 225,267, dated March 9,1880,

Application filed July 10, 1879. y

T0 all 'whom it may concern:

Beit known that I, ACHILLE BATAILLE, of the city and State of New York,have invented an Improvement in Flexible Joints for Pipes, of which thefollowing is a specification.

Pipe-couplings have been made so as to be kept tight by the internalpressure acting upon a packing, and in some instances the pipe can berevolved at the coupling, and in other instances the angle of one partof the pipe to the other can be varied.

My iiexible joint is made with reference to allowing the angle betweenthe two pipes to be varied, and so that the pressure will keep the jointtight. Thereby the joint can be easily used with air-brakes uponrailway-cars, or under any other circumstances where the joint isrequired to yield' freely in one direction, and the pressure will renderthe joint tight even when it moves freely1 or is loose whenl there is nopressure.

I make use of a ring-nut Within the coupling, to connect the two shells,and there is a tubular bearing to keep the shells in the proper relativepositions and an annular bearing against'which the pressure acts to keepthe parts of the flexible joint steam or air tight when in use.

In the drawings, Figure lis a section of Vthe exible joint, and Fig. 2is a plan of the same with the cap removed. The other figures representmodifications of the devices, and are separately referred to.

The coupling-shells c and b are of suitable size, and to these the pipescland care permanently connected by any suitable device, such as ascrew. The tubular thimble f projects from one side of the case a, andthe case b sets over this thimble, and the nut h prevents the partsbecoming separated, but allows the shell b to turn freely upon thethimble f and shell a.

There is a cap, Z, to the shell b, and this is removed when the nut h isscrewed upon the thimble f. Upon the inside of the cap Z is aninward-proj ecting tubular bearing, m, that sur-` rounds the inner endof the thimble f, so as Vto cause the two shells to turn true, the oneonk the other, and prevent the parts becoming displaced in use, and thisbearing m has open- 5o ings or is formed of open-work, so as' not totight at the joint between the ring i and thimble f when the nut hisscrewed tightly upon the same.

The portion of the case b which is between the bearing-ring t' and thecase or is free to turn, but it bears against the surface of thebearingring, and it is necessary that the surface of the Vbearing-ringbe ground or madeto fit steam-tight at its bearing upon the part 3 ofthe case b.

The bearing-surface of the bearing-ring i may be flat, curved, orconical. This surface is shown as conical in the sections, Figs. 3, 4,and 5; but in Fig. 3 the inclination of the conical surface is thereverse to what it is in Fig. 5, the bearing-ring being thickest at itsouter edge. j The curved surface may be used in place of either of theconical surfaces. In Fig. l the bearing-ring 'L' is of the samethickness throughout, both faces being iiat.,

It is to be understood that when the fluid or liquid under pressure actswithin the shellsa and b the tendency is to separate them and bring thesurface 3 forcibly into contact with the bearing-ring, and make a tightjoint at this place. If, on the contrary, there is a vacuum action inthe pipes the atmospheric pressure will force the shells toward eachother, and the bearing-ring requires to be placed the other side up, asshown in Fig. 4, and the bearing portion 3 of the case b has to 'be aseparate ring, screwed into the shell b.

In some instances I make use of the secondary bearing-ring, o, (shown inFig. 1,) the same having annular ribs 4 and 5, which bear into groovesthat are turned in the back surface of the bearing-ring fi and shell b,near the edge of said ring fi. In this instance the internalpressureforces the annular ribs upon the surfaces as well as keeping the surface3 tightly against the annular bearing i.

The surfaces of the shells ci and b that are in contact may be providedwith annular ribs IOO and grooves, as at 6, to take any lateral strain2.
